In GeoGebra 4.4, the CAS View supports exact versions of some of the geometry commands, and there is now some support for parametric curves. Here are some examples you can try :)


Radius[x^2+y^2=1/sqrt(pi)]

Center[x^2+y^2=1/sqrt(pi)]

Circumference[x^2+y^2=1/sqrt(pi)]

Distance[(0.5,0.5),x^2+y^2=1]

Distance[(0,4),y=x^2]

Distance[(0,0),x+2y=4]

Distance[x+2y=4,x^2+y^2=1]

Distance[(a,b),p x + q y = r]
